Abstract

Nowadays, natural fibers have become one of the most widely utilized materials due to its abundance, cheaper cost, sustainability, and environmental friendliness in contrast to artificial fibers. Natural fibers are increasingly being substituted for synthetic fibers in manufacturing green panels because to the expensive cost of synthetic fiber. In this study, the manufacturing of green panels will be done in order to determine the best stacking order based on the effectiveness of the laminate hybrid made of jute and fiberglass as reinforcement and epoxy resin as the matrix. Therefore, for each distinct fiber and hybrid sequence, 4 separate stacking layers will be carried out utilizing a straightforward hand layup cold press technique. Additionally, this study will undergo testing in line with ASTM standard. The mechanical characteristics and complementary nature of fibreglass (G-24) and jute fibre (J-24), highlight their use together in green panel applications. In order to maintain the environmental benefits of hybridization, at least 50 % of the fibre content must be jute, with the remaining portion being fibreglass. J-24 is thicker than G-24 due to its inherent fibre density, as shown by the thickness comparison. The reduction in ultimate tensile strength that comes with hybridization with fewer fibreglass layers illustrates the trade-off for a composition that is more favourable to the environment. Flexural strength studies identify H-J12G12 as the most promising hybrid composite for green panels, while tensile testing reveals variable forces, with G-24 displaying the strongest force. Impact testing confirms that H-J16G8 is the most promising hybrid, providing outstanding resistance to impacts and energy absorption. In applications where strength and environmental sustainability are required, the results support the strategic use of hybridization in green composites.
